Both take a lot of skill to be good. For pvp you prolly will want to go shammy because rdruids cant handle burst damage like shamans can. Druid have a better shapshift as it drops slows and snares but shammies totems are also really nice. rshaman GHW will heal for a shit ton but they are not a very mobile healer where as druids are one of the most mobile healers, but they are mostly hots and lack big heals
